7.13.2 Fuel Tank
Each wing is equipped with an integral fuel tank. The fuel line of each tank is equipped
with a removable coarse fuel filter. The fuel filler caps can be locked.
A drain valve is located at the lowest point of each fuel tank. Another drain valve is
located at the firewall. All drain valves can be easily operated.
A drainage cup is located on the inside of the baggage compartment door.
Fuel is supplied to the engine by a mechanical fuel pump built into the engine. The
mechanical fuel pump has an integrated fuel strainer. When needed, an electrical fuel
pump can also be switched on.
The electrical fuel pump is controlled by a switch on the instrument panel labeled
Fuel
Pump
.
The electrical fuel pump must be turned on during take-off and landing, when
low fuel pressure is suspected or during critical phases of flight.
Too low fuel pressure (below 2.2 PSI/0.15 bar) is detected by a pressure probe and
annunciated on the MVP-50P-AQ. When the fuel pressure is low, the electrical fuel
pump must be turned on.
NOTE
When flying near the ground, such as during take-off and landing or when low fuel
pressure is indicated, the electrical fuel pump must be turned on
The fuel tanks are vented via a vent line outlet located in the winglets.
7.13.3 Fuel Selector / Shut-Off Valve
The fuel selector is conveniently mounted on the control panel in full view of the pilots.
The red, arrow-shaped selector handle has a LEFT, RIGHT, and OFF-position. Each
position is notched and has a self-centering mechanism using a spring-loaded pin. The
selector handle points to the chosen position.
In both normal operating positions (LEFT/RIGHT), the fuel supply and corresponding
return line of the selected fuel tank are opened. The fuel supply and return line of the
other fuel tank are closed.
It is recommended to keep both tanks at approximately the same fuel level.
NOTE
Recommendation: Fuel tanks should be switched at least every 60 minutes.
When the fuel selector valve is in the OFF position, the fuel flow in the supply and return
lines is interrupted and functions as a fuel shut-off valve.
To switch the valve into the OFF-position, the knob located at the top of the handle must
be PULLED while simultaneously turning the handle clockwise into the OFF-position.
